Badger, I gave up a year ago with the slip-fits on #139.
Swaging the header connections is a good workaround, I've heard, but I don't have access to that kind of machining skills here. A sharp L-curve, under internal pressure and a lot of heat, is gonna flex. I would rather it flex at the header/sidepipe joint than... somewhere expensive.
I even tried packing steel wool into the joint and using 2 big radiator clamps dogged down TIGHT to muffle the joint blow-by, it worked well for about 30 minutes, but flexing and vibration wiped my kludge out.
I just live with the noise from under the hood, I'm probably the only one that notices it in my little part of the woods.
